So hot, in fact, that the Post says a bidding war has broken out. Agent Richard Abate is said to be talking to publishers about a book by Fey. (This is not Palin, now, mind you – this is simply her double, Tina Fey.)

Although there's long been interest in a Tina Fey book project, the Post says, Fey's recent appearances as the faux Palin on Saturday Night Live have turned Fey into such a star that anything connected to her is ultra-valuable property.

That's why one publisher is said to have offered $5-million for a book by Fey while another is rumored to have responded with a $6-million bid.

It's not clear whether such a book would be a memoir or a Nora Ephron-style piece of humorous writing. Perhaps it doesn't matter.
